Hello Buddies,
Sharing a quick-start reference which I came across while working with Git repo.
Here are some quick commands -
CONFIGURE TOOLING 
Configure user information for all local repositories -
$ git config --global user.name "[name]" 
Sets the name you want attached to your commit transactions 
$ git config --global user.email "[email address]" 
Sets the email you want attached to your commit transactions 
$ git config --global color.ui auto 
Enables helpful colorization of the command line output
CREATE REPOSITORIES 
Start a new repository or obtain one from an existing URL -
$ git init [project-name] 
Creates a new local repository with the specified name 
$ git clone [url] 
Downloads a project and its entire version history
MAKE CHANGES 
Review edits and creates a commit transaction -
$ git status 
Lists all new or modified files to be committed 
$ git add [file] 
Snapshots the file in preparation for the versioning 
$ git reset [file] 
Un-stages the file, but preserves its contents 
$ git diff 
Shows file differences that are not yet staged 
$ git diff --staged 
Shows file differences between the staging and the last file version 
$ git commit -m "[descriptive message]" 
Records file snapshots permanently in the version history
GROUP CHANGES 
Name a series of commits and combine completed efforts -
$ git branch 
Lists all the local branches in the current repository 
$ git branch [branch-name] 
Creates a new branch 
$ git checkout [branch-name] 
Switches to the specified branch and updates the working directory 
$ git merge [branch] 
Combines the specified branch’s history into the current branch 
$ git branch -d [branch-name] 
Deletes the specified branch
REFACTOR FILENAMES 
Relocate and remove versioned files -
$ git rm [file] 
Deletes the file from the working directory and stages the deletion 
$ git rm --cached [file] 
Removes the file from version control but preserves the file locally 
$ git mv [file-original] [file-renamed] 
Changes the file name and prepares it for the commit
REVIEW HISTORY 
Browse and inspect the evolution of project files -
$ git log 
Lists version history for the current branch 
$ git log --follow [file] 
Lists version history for a file, including renames 
$ git diff [first-branch]...[second-branch] 
Shows content differences between the two branches 
$ git show [commit] 
Outputs metadata and content changes of the specified commit
SUPPRESS TRACKING 
Exclude temporary files and paths -
*.log build/ temp-* 
A text file named .gitignore suppresses accidental versioning of files and paths matching the specified patterns
$ git ls-files --other --ignored --exclude-standard 
Lists all ignored files in this project
REDO COMMITS 
Erase mistakes and crafts replacement history -
$ git reset [commit] 
Undoes all commits after [commit], preserving changes locally 
$ git reset --hard [commit] 
Discards all history and changes back to the specified commit
SAVE FRAGMENTS 
Shelve and restore incomplete changes -
$ git stash 
Temporarily stores all modified tracked files 
$ git stash list 
Lists all stashed changesets 
$ git stash pop 
Restores the most recently stashed files 
$ git stash drop 
Discards the most recently stashed changeset
SYNCHRONIZE CHANGES 
Register a repository bookmark and exchange version history -
$ git fetch [bookmark] 
Downloads all the history from the repository bookmark 
$ git merge [bookmark]/[branch] 
Combines bookmark’s branch into the current local branch 
$ git push [alias] [branch] 
Uploads all the local branch commits to GitHub 
$ git pull 
Downloads bookmark history and incorporates the changes

Happy Coding!!
